1) The document discusses testing of low rank, high moisture coal from Indonesia stockpiled under ambient conditions to understand how its total moisture content can be reduced naturally.
2) Small-scale drying tests showed an average 27% weight loss over 22 days, indicating potential for significant moisture reduction. Larger stockpile tests found drainage allowed moisture loss of 0.7-1.7% daily, but overall moisture increased with rain periods.
3) For maximum drying benefit, coal would need sheltering from rain. Without considering weather effects, natural drainage over 18-25 days could assist in moisture reduction for the high moisture low rank coal.

Annual atmospheric corrosion rate and dose-response function for carbon steel...Carlos Arroyave
This paper presents an assessment on the behavior of plain carbon steel exposure to the atmosphere of Bogotá. The main climate and environmental parameters, including relative humidity (RH), temperature (T), sulphur dioxide deposition (DSO2) and particulate matter deposition (DPM) were measured. Furthermore, mass loss of AISI/SAE 1006 plain carbon steel coupons was measured along one year. In this case, coupons were exposed in eight test sites located across the city of Bogotá. Results show that the corrosion rate of carbon steel is less than 35 μm yr–1 after one year. It was found that the west part of the city has the greatest aggressivity, which has the highest levels of DPM and DSO2, related with the characteristics of the anthropogenic activities distribution across the city. A dose-response function of plain carbon steel exposure to the atmosphere of Bogotá, based on RH, T and DSO2, was obtained.

Soot production and particle size distribution from in situ burning of crude ...Vasilis Vasou
ABSTRACT:
In situ burning has proven to be an effective response for oil spills in Arctic conditions. However the incomplete combustion of oil, due to an incomplete chemical reaction between the fuel and oxygen, lead to the production of solid and gaseous products, such as particulate matter (soot), polycyclic aromatic hydrocarbons (PAHs) and volatile organic compounds (VOCs). Several studies have suggested a link between the presence of these compounds and several diseases; of high concern are the particles smaller than 10 μm (PM10) that can penetrate deep in the lungs, hence the importance to understand the key parameters affecting particulate production and size. The aim of this study was to evaluate the influence of oil viscosity, pool size
diameter and the presence of ice on the production of soot and size of the particles emitted. Two oils were used: DUC and REBCO, with a viscosity of 5 cP and 16 cP respectively. The scale effect was studied on two pools with diameters of 15 and 26 cm. The analysis was divided in three phases: a first outdoor phase performed in Greenland, where in situ burning experiments were performed using both oils and pools, in fresh and salt water and with the presence of ice. The smoke was collected on 2 μm pore size filters and later analysed. The same experiments were later performed in indoor conditions and the concentration of carbon monoxide was measured using optical analysis. In the last phase, the soot collected on the filters was observed with the help of the
scanning electron microscope (SEM). A positive correlation between the pool size and the amount of soot produced was observed, connected with a peak in carbon monoxide production during the vigorous burning phase, while viscosities has shown different behaviour depending on the pool size. The particles size seems to be independent of both the viscosity and the pool diameter. However the presence of PM10 was observed during combustion in ice affected water.
Distribution and mobility of lead and zinc atmospheric depositions in industr...INFOGAIN PUBLICATION
Heavy metal contamination is a severe environmental problem. Knowledge of the total heavy metals contents of soils is a necessary step for making an accurate appraisal and quantitative evaluation of the extent of contamination, indeed, wet and dry atmospheric deposits, plays an important role in the cycle of semi-volatile contaminants [1]. Metallurgical industries release heavy metals into the atmosphere, these last, clump together to form fines particles suspended in the air, these metals can be transported by wind via aerosol or aqueous pathway and deposited in the soil. The main aim of this work was to study the mobility and fate of lead and zinc from atmospheric deposits in contaminated soil from the foundry (ALFET) in industrial zone of Tiaret (Western Algeria) and to determine the effect of physicochemical parameters of the soil on their mobility in the topsoil. Physicochemical analysis of 35 soil samples have shown that zinc and lead levels contents in the surface layer soil (0-30 cm) vary depending on the pH, total limestone (CaCO3) and the soil water content. Results clearly show that soil texture and fine fraction (clay and sand) significantly influence mobility of Pb and Zn in soil.
MHD Chemically Reacting and Radiating Nanofluid Flow over a Vertical Cone Emb...IJLT EMAS
In this study, we examine the combined effects of
thermal radiation, chemical reaction on MHD hydromagnetic
boundary layer flow over a vertical cone filled with nanofluid
saturated porous medium under variable properties. The
governing flow, heat and mass transfer equations are
transformed into ordinary differential equations using similarity
variables and are solved numerically by a Galerkin Finite
element method. Numerical results are obtained for
dimensionless velocity, temperature, nanoparticle volume
fraction, as well as the skin friction, local Nusselt and Sherwood
number for the different values of the pertinent parameters
entered into the problem. The effects of various controlling
parameters on these quantities are investigated. Pertinent
results are presented graphically and discussed quantitatively.
The present results are compared with existing results and found
to be good agreement. It is found that the temperature of the
fluid remarkably enhances with the rising values of Brownian
motion parameter (Nb).

ABSTRACT: Species of the Centrospermeae occurring at different altitudes were analyzed for δ13C values and assigned for graphical representation. The aridity of the study area was evident as defined using the Klimadiagramm. Climatic data was studied and represented on graphs for interpretation. The frequency ofδ 13C values of the species at different altitudes, namely 500m a.s.l., 1000m a.s.l., 1500m a.s.l., 2000m a.s.l., 2500m a.s.l., 3000m a.s.l., 3500m a.s.l. and 4000m a.s.l., are presented on graphs. The data show thatδ13C values is a good predictor of spatial diversity and shift of the species along the altitudinal gradient of environmental factors.There is phenomenal trend such that δ13C values distribution along altitudinal differentiation the values of -10.60‰, to -16.65‰, -17.75‰ to -18.87‰, and -18.89‰ to -32.42‰ correspond to the species at low altitudes (0m a.s.l. – 1500m a.s.l.), intermediate altitude (1,550m a.s.l.-1,700m a.s.l.) and high altitude (1,800m a.s.l. – 4200m a.s.l.0, respectively. The inverse correlation between temperature and rainfall defines the causal climatic factors affecting C3 and C4 species along the altitudinal gradient. The occurrence of the transition zone between temperature and rainfall mirror that between the relative abundance of the C3 and C4 species along the altitude. This floristic data predict NAD-ME, NADP-ME AND PEP-CK types of monocot-dicot transition along the altitude with respect to bioproductivity in the tropics.
Effect of CO2 sequestration on soil liquefaction in geological pitsijiert bestjournal
This paper deals with review of the previous related research on evaluation of soil liquefaction due to Carbon sequestration by various Carbon Capture Sequestration processes in geological pits. It provides critical literature recommendations on evaluation of soil liqu efaction potential assessment. The detection of soil liquefaction by using seismic records has been developed by various researchers. With this information,the evaluation of soil liquefaction are well under stood and this lead to a more precise and confident output. Gaining support for CCS will require engaging the interest and building the support of a variety of stakeholders,each with differ ent perspectives and goals. Although,CCS builds upon a technology base developed over more than half a century by the oil and gas industry. In the past,the industrially released CO 2 had been introduced to ocean which was harming the aquatic animals. In view of this,the sequestration of CO 2 into ocean was internationally banned. Hence,now much of the Carbon sequestration process is done by various industries in geolog ical pits. This creates a major threat to the earth quake problems worldwide. With the enhanced frequenc y of earthquakes all around the world,it is presumed by many environment scientists that the CO 2 sequestration pits leads to soil liquefaction and hence it results in more frequent earth quakes. T herefore,this paper summarises,different methods to evaluate liquefaction potential of soil by usi ng studies from seismic waves generated in earth,it is also propose it is also explains different me thodology for an eco friendly technology to reduce CO 2 from environment.
CFD Analysis on Forced Convection Heat Transfer of KNO3–Ca NO3 2 TiO2 Molten ...YogeshIJTSRD
Nanotechnology has been a global movement in recent decades. The possibility of manipulating atomic and molecular materials has resulted in previously unimaginable properties and characteristics. The molten salt nanofluid created by integrating nanoparticles into molten salt has a much higher specific heat capacity and thermal conductivity than the base molten salt, resulting in a higher heat storage density and lower heat storage cost than the base molten salt. Since the discovery of molten salt nanofluids excellent thermal properties, the heat transfer of molten salt nanofluid has piqued engineers curiosity. In this analysis, the forced convection heat transfer of KNO3–Ca NO3 2 TiO2 molten salt nanofluid in circular tube was investigated using a 3 dimensional numerical 3 D simulation. The simulation programme ANSYS 17.0 was used for study of the heat transfer physiognomies of a KNO3–Ca NO3 2 TiO2 molten salt nanofluid in circular tube. The effect of nanofluid were measured and observed to influence the heat transfer and flow of fluids in a heat exchanger. The following conclusions can be drawn based on the provided results The KNO3–Ca NO3 2 TiO2 molten salt nanofluid performed slightly better in forced convection heat transfer than the KNO3–Ca NO3 2 SiO2 molten salt nanofluid under the same working conditions. KNO3–Ca NO3 2 TiO2 molten salt nanofluid had a 14.79 percent higher Nusselt number than KNO3–Ca NO3 2 SiO2 molten salt nanofluid.

Use of Hybrid Nanofluid to Increase Heat Transfer Performance of Double Pipe ...ijtsrd
In present work, forced convection of a turbulent flow of, Al2O3 water nanofluid and Al Al2O3 water hybrid nanofluid a new advanced nanofluid composited of Al and Al2O3 nanoparticles through a double pipe heat exchanger is numerically analyzed. The solid model of the double pipe heat exchanger is created in design modular and analyzed by the computational software ANSYS 16.0.This work examines the effects of these two fluids as the working fluids, a wide range of Reynolds number 20000 = Re = 60000 and also the volume concentration 0.25 , and 0.5 on heat transfer and hydrodynamic performance. The finite volume discretization method is employed to solve the set of the governing equations. The results indicate that employing hybrid nanofluid improves the heat transfer rate with respect to nanofluid. However, the average increase of the average Nusselt number when compared to nanofluid in Al Al2O3 water hybrid nanofluid is 14 and the amount for the average increase of heat transfer coefficient would be 27.5 .

Application of Langmuir-Hinshelwood Model to Bioregeneration of Activated Car...IOSR Journals
Environmental pollution, high cost and high energy consumption associated with thermal regeneration of activated carbon polluted with hydrocarbon necessitated the search for a better way of regenerating activated carbon, bioregeneration. Spent granular activated carbon was regenerated having been initially characterized using cultured Pseudomonas Putida. The rate of bioregeneration was studied by varying the volume of bacteria from 10ml, 20ml, 30ml and 40ml. The regeneration temperature was also varied from 25oC to ambient temperature of 27oC, 35oC and further at 40 and 45oC over a period of 21 days. The experimental results showed clear correlation when validated using the Langmuir-Hinshelwood kinetic model. The experiment at ambient temperature showed a negative correlation due to the fluctuation in the ambient temperature unlike all other experiment where temperature was controlled in an autoclave machine.

The application of cooking gas refrigerants in refrigeration system is considered to be a potential way to improve
energy efficiency and to encourage the use of environment-friendly refrigerants. Refrigeration operation has
been met with many challenges as it deals with environmental impact, how it affects humans and how it
contributes to the society in general. Domestic refrigerators annually consume several metric tons of traditional
refrigerants, which contribute to very high Ozone Depletion Potential (ODP) and Global Warming Potential
(GWP). The experiment conducted employs the use of two closely linked refrigerants, R600a (Isobutene) and
cooking gas which is varied in an ideal refrigerant mixture of 150 g of refrigerant and 15 ml of lubricating oil (to
a rating of 40 wt % expected in the compressor). The Laboratory process involved the use of Gas
Chromatography machine to ascertain the values of the mole ratio, molecular weight and critical temperatures.
Prode properties and Refprop softwares were used to ascertain other refrigerant properties of the mixture. The
results indicated that the mixture of R600a with lubricant confirm mineral oil as being the most appropriate for
the operation. The experimental results indicated that the refrigeration system with cooking gas refrigerant
worked normally and was found to attain high freezing capacity and a COP value of 2.159. It is established that
cooking gas is a viable alternative refrigerant to replace R600a in domestic refrigerators. Hence, its application
in refrigerating systems measures up to the current trend on environmental regulations with hydrocarbon
refrigerants
In this project we basically studied scope of this project, its feasibility and market assessment, raw material availability, different routes to produce Syngas and their comparison, process selection and its complete description, its P&ID, and environmental consideration.
Actuality Test - A Technique for Expeditious Agglomeration Detection in a Lab...AJSERJournal
This research has concentrated on the application of actuality/reality test for speedy confirmation of
lumps/agglomerates formation thereby emphasizing the roles of alkali metals and silica in agglomeration during the
combustion of some selected biomass fuels (miscanthus, white wood, and willow) in a laboratory-scale fixed bed.
Biomass fuels are CO2 neutral and very rich in alkali metals especially potassium, K and sodium. Potassium played
predominant roles in the agglomeration formation of these selected biomass fuels. During the experiments, huge
agglomerates were formed at a lower melting temperature of 350 0
C when potassium hydroxide, KOH and silica sand
were heated together directly (reality test) in the combustion chamber (Gooch crucible). Harder and tougher
agglomerates were produced at 502 0
C. This attested to the fact that, agglomerates are produced from the formation
of a low melting temperature eutectic compound (alkali-silicate) in the form of K-silicate. The eutectic compound has a
lower melting temperature than the melting temperature of the parent materials - the alkali metals or the silica from
sand, which is the bed material. It therefore melts sharply in the bed and formed lumps in form of agglomerates. The
results of this research have indicated that, potassium K and silica SiO2 are very important in the formation of
agglomerates during the combustion of biomass fuels. Gooch ceramic crucible is a very good combustion chamber for
the combustion of biomass fuels experiments/tests in a laboratory – scale fixed bed. It accommodated more heat
distribution into the combustion chamber than the conventional ceramic crucible.
ENHANCEMENT OF THERMAL EFFICIENCY OF NANOFLUID FLOWS IN A FLAT SOLAR COLLECTO...Barhm Mohamad
Flat plate solar collector (FPSC) is popular for their low cost, simplicity, and ease of installation and operation. In this work, FPSC thermal performance was analyzed. It's compared to diamond/H2O nanofluids. The volume percentage and kind of nanoparticles are analyzed numerically that validation with experimental data available in the literature. The hot climate of Iraq is employed to approximate the model. The numerical study is performed by using ANSYS/FLUENT software to simulate the case study of problem. Due to less solar intensity after midday, temperatures reduction. The greatest collector thermal efficiency is 68.90% with 1% ND/water nanofluid, a 12.2% increase over pure water. The efficiency of 1% nanofluid is better than other concentrations because of a change in physical properties and an increase in thermal conductivity. Since the intensity of radiation affects the outlet temperature from the solar collector and there is a direct link between them, this increases the efficiency of the solar collector, especially around 12:30 pm at the optimum efficiency.

A Strategic Approach: GenAI in EducationPeter Windle
Artificial Intelligence (AI) technologies such as Generative AI, Image Generators and Large Language Models have had a dramatic impact on teaching, learning and assessment over the past 18 months. The most immediate threat AI posed was to Academic Integrity with Higher Education Institutes (HEIs) focusing their efforts on combating the use of GenAI in assessment. Guidelines were developed for staff and students, policies put in place too. Innovative educators have forged paths in the use of Generative AI for teaching, learning and assessments leading to pockets of transformation springing up across HEIs, often with little or no top-down guidance, support or direction.
This Gasta posits a strategic approach to integrating AI into HEIs to prepare staff, students and the curriculum for an evolving world and workplace. We will highlight the advantages of working with these technologies beyond the realm of teaching, learning and assessment by considering prompt engineering skills, industry impact, curriculum changes, and the need for staff upskilling. In contrast, not engaging strategically with Generative AI poses risks, including falling behind peers, missed opportunities and failing to ensure our graduates remain employable. The rapid evolution of AI technologies necessitates a proactive and strategic approach if we are to remain relevant.
2024.06.01 Introducing a competency framework for languag learning materials ...Sandy Millin
http://sandymillin.wordpress.com/iateflwebinar2024
Published classroom materials form the basis of syllabuses, drive teacher professional development, and have a potentially huge influence on learners, teachers and education systems. All teachers also create their own materials, whether a few sentences on a blackboard, a highly-structured fully-realised online course, or anything in between. Despite this, the knowledge and skills needed to create effective language learning materials are rarely part of teacher training, and are mostly learnt by trial and error.
Knowledge and skills frameworks, generally called competency frameworks, for ELT teachers, trainers and managers have existed for a few years now. However, until I created one for my MA dissertation, there wasn’t one drawing together what we need to know and do to be able to effectively produce language learning materials.
This webinar will introduce you to my framework, highlighting the key competencies I identified from my research. It will also show how anybody involved in language teaching (any language, not just English!), teacher training, managing schools or developing language learning materials can benefit from using the framework.

June 3, 2024 Anti-Semitism Letter Sent to MIT President Kornbluth and MIT Cor...Levi Shapiro
Letter from the Congress of the United States regarding Anti-Semitism sent June 3rd to MIT President Sally Kornbluth, MIT Corp Chair, Mark Gorenberg
Dear Dr. Kornbluth and Mr. Gorenberg,
The US House of Representatives is deeply concerned by ongoing and pervasive acts of antisemitic
harassment and intimidation at the Massachusetts Institute of Technology (MIT). Failing to act decisively to ensure a safe learning environment for all students would be a grave dereliction of your responsibilities as President of MIT and Chair of the MIT Corporation.
This Congress will not stand idly by and allow an environment hostile to Jewish students to persist. The House believes that your institution is in violation of Title VI of the Civil Rights Act, and the inability or
unwillingness to rectify this violation through action requires accountability.
Postsecondary education is a unique opportunity for students to learn and have their ideas and beliefs challenged. However, universities receiving hundreds of millions of federal funds annually have denied
students that opportunity and have been hijacked to become venues for the promotion of terrorism, antisemitic harassment and intimidation, unlawful encampments, and in some cases, assaults and riots.
The House of Representatives will not countenance the use of federal funds to indoctrinate students into hateful, antisemitic, anti-American supporters of terrorism. Investigations into campus antisemitism by the Committee on Education and the Workforce and the Committee on Ways and Means have been expanded into a Congress-wide probe across all relevant jurisdictions to address this national crisis. The undersigned Committees will conduct oversight into the use of federal funds at MIT and its learning environment under authorities granted to each Committee.
• The Committee on Education and the Workforce has been investigating your institution since December 7, 2023. The Committee has broad jurisdiction over postsecondary education, including its compliance with Title VI of the Civil Rights Act, campus safety concerns over disruptions to the learning environment, and the awarding of federal student aid under the Higher Education Act.
• The Committee on Oversight and Accountability is investigating the sources of funding and other support flowing to groups espousing pro-Hamas propaganda and engaged in antisemitic harassment and intimidation of students. The Committee on Oversight and Accountability is the principal oversight committee of the US House of Representatives and has broad authority to investigate “any matter” at “any time” under House Rule X.
• The Committee on Ways and Means has been investigating several universities since November 15, 2023, when the Committee held a hearing entitled From Ivory Towers to Dark Corners: Investigating the Nexus Between Antisemitism, Tax-Exempt Universities, and Terror Financing. The Committee followed the hearing with letters to those institutions on January 10, 202
